Uses Cloudflare's free, public speed-test network (the same infrastructure behind speed.cloudflare.com) to download and upload real test data and time it — a genuine throughput measurement, not a simulation. Honest scope: unlike Ookla-based speedtest.net, there's no manual multi-server picker — every test hits Cloudflare's nearest edge automatically (shown as "Test Server" once a test finishes). IP/ISP lookup uses the free ipwho.is API. Test history is saved only in your browser (localStorage), never sent anywhere. No sign-up, no key.
